1.3 Peripheral equipment

Required inputsThe Simrad SP70 sonar system requires input from both a speedlog and a course gyro. Inaccurate data from either of theseinstruments will result in an incorrect indication of vessel andtarget movement.

Speed log

The speed log parameters are:• Pulse log: 200 pulses / nm.• Serial line, standard NMEA 0183, RS-232→ Also refer to (D)GPS below.

Course gyro

The course gyro parameters are:• Serial line, standard NMEA 0183, RS-232An optional gyro interface box for converting the followingsynchro and stepping gyro signals can be ordered from Simrad:• 3-phase synchro signal, 20 to 150 V L-L, 50/60/400 Hz, gearration 1:360 or 1:180

• 3-phase stepper signal, 20 to 150 V L-L, gear ration 1:360 or1:180

→ Refer to page 5 for the Simrad order number.

Additional inputsIn addition to the pulse log input described above, the SP70 sonarprovides a total of four RS-232 serial lines. Since one is used tointerface the course gyro, the remaining three serial lines may beused for:• Differential Global Positioning System - (D)GPS• Echo sounder• Purse seine system• Trawl system• Radio buoy system

Differential Global Positioning System - (D)GPS

A (D)GPS may be interfaced with the Simrad SP70 sonar toestablish the vessel’s position and provide cursor and markerlatitude and longitude.

Introduction

7851-164336 / C

Note that in addition to navigational data, the (D)GPSmay also beused for the input of speed log information. Most (D)GPS areequipped to present course information, but this data is generallytoo inconsistent to provide a stable sonar presentation.The (D)GPS parameters are:• GPS data: RS-232 Serial line, standard NMEA 0183.

Echo sounder

To provide depth information on the catch control page of thesonar’s display, echo sounders may be connected:• RS-232 Serial line, standard NMEA 0183

Purse seine system

To provide purse seine depth information on the sonar’s display,the following Simrad purse seine system may be connected:• Simrad PI30 Purse seine system (RS-232)

Trawl system

To provide trawl information on the sonar’s display, one of thefollowing Simrad trawl systems may be connected:• Simrad FS903 Trawl sonar system (RS-232)• Simrad FS3300 Trawl sonar system (RS-232)• Simrad ITI Integrated Trawl Instrumentation system (RS-232)

1.5 General safety rulesThe system operates on 115 and/or 230 / 380 / 440 Vac, 50/60 Hz.

WARNING This voltage can be lethal.

The following safety precautions must be followed at all timesduring installation and maintenance work:

• Always switch off all power before installation ormaintenance.Use the main circuit breaker, and label the breaker with awarning sign that informs others that maintenance orinstallation work is being carried out on the system.

• Read and understand the first aid instructions for electric shock.

• For safety reasons during troubleshooting on the equipmentwith power ON, two persons should always be present.

• Whenever maintenance is carried out, it is essential that a firstaid kit is available, and that the maintenance personnel arefamiliar with the first aid instructions for electrical shock.

• The various parts of the system are heavy. Make sure that theappropriate tools and certified lifting equipment are available,and that the personnel are trained in installation andmaintenance work.

1.6 Installation requirements

Responsibility and approvalThe Simrad SP70’s Hull Unit sleeve has been approved by DetNorske Veritas (DNV) Classification society.

Individual Hull Unit installations must be approved on acase-by-case basis with regard to the vessel’s national registry andcorresponding maritime authority. The shipowner and shipyardperforming the installation are responsible for obtaininginstallation approval.

Supply powerThe supply voltage to the equipment is to be kept within ±15% ofthe installation’s nominal voltage. Maximum transient voltagevariations on the main switchboard’s bus-bars are not to exceed-15% to +20% of the nominal voltage (except under faultconditions).

Simrad strongly recommends that the SP70 sonar be poweredusing an Uninterruptible Power Supply (UPS). The UPS shouldhave the capacity to independentlymaintain power to the sonar fora minimum of 10 minutes. This ensures that the system can beswitched off in a controlledmanner in the event of a power failure.

Environmental requirements

Vibrations

If the equipment is expected to be exposed to excessive vibrationfor extended periods, special dampening precautions must betaken.

Temperature and humidity

All equipment, unless otherwise specified, must be protected fromtemperature extremes and excessive humidity.→ Refer to page 151 for more information.

Compass deviationOnce the installation is complete, the vessel must be swung withthe sonar in both the operative and inoperative modes. Theshipowner and captain are responsible for updating the deviationtable accordingly with regard to the vessel’s national registry andcorresponding maritime authority.

Introduction

11851-164336 / C

Noise sourcesThe vessel’s hull, rudder(s) and propeller(s) should be thoroughlyinspected in dry dock prior to installation. Roughness below thewater-line deformities in the shell plating and protruding obstaclescan create underwater noise. These sources of turbulence must besmoothed or removed as best as possible. It is especially importantthat the propeller(s) is not pitted or damaged.

Dry dockingMake sure that ample clearance under the sonar trunk and/orprotection blister is provided when dry docking the vessel. Avoidlocating supporting blocks or structures in the vicinity of thisequipment.

Note The location of the sonar trunk and/or protection blister must benoted on the vessel’s docking plan for future reference.

WiringThe cable from the wheelhouse to the sonar room must besupported and protected along its entire length using conduitsand/or cable trays. Note that the cable must not be installed in thevicinity of high-power supplies and cables, antenna cables or otherpossible sources of interferences.

1.7 Equipment handling

IntroductionThis chapter describes how to transport, pack and unpack, clean,preserve and store electronic, electro-mechanical and mechanicalunits supplied by Simrad AS.The units may be supplied as spare parts, or as parts of a delivery.

Transportation

General specifications

Unless otherwise stated in the accompanying documentation,electronic, electro-mechanical and mechanical units supplied bySimrad can be transported using all methods approved for delicateequipment; e.g. by road, rail, air or sea. The units are to betransported in accordance with general or specific instructions forthe appropriate unit(s), using pallets, transport cases, or cartonboxes as appropriate.

Note Special local restrictions concerning air transportation may beapplied to units containing certain types of batteries. The unitsshould be checked and the regulations investigated by thepacker/shipper before the unit is dispatched.

Local transportation

All local transportation must be carried out according to the samespecifications as for the initial delivery. In general, all units mustbe handled with care. The carton or case containing the equipmentmust be kept dry at all times, and must be sheltered from theweather. It must not be subjected to shocks, excessive vibration orother rough handling.The carton or case will normally be marked with text or symbolsindicating which way up it is to be placed. Follow any instructionsgiven and ensure the case is always placed with its “top”uppermost.The carton or case must not be used for any purpose for which itwas not intended (e.g. step, table, etc.), and in the absence of otherinformation, no other cartons or cases must be stacked on top of it.

Lifting

A heavy crate will normally be marked with its weight, and theweights of other cartons or crates will normally be entered on thepacking list.• Always check the weight of a crate before attempting to lift it.• Always use lifting apparatus that is certified for the load.

Introduction

13851-164336 / C

Heavy units may be equipped with lifting lugs for transportationby crane within the workshop or installation area. Before a craneis used, check:• The applicable weight certificate for the crane.

• The security of the lifting lugs.

Ensure that all available lifting lugs are used. Ensure the unitremains under control during the operation to avoid damage to theunit, equipment or personnel.Heavy units may be transported using a fork-lift truck. Specialattention must then be paid to the position of the unit’s centre ofgravity. The units must be properly secured to the truck.

Initial preservation

Introduction

When a system, a unit or a spare part has been delivered to thecustomer, it may be subject to long-time storage prior toinstallation and use. During this storage period, certainspecifications must be met.The equipment must be preserved and stored in such a way that itdoes not constitute any danger to health, environment or personalinjury.Specific specifications are presented below.→ For further information about storage, refer to page 17.→ For further information about re-packing, refer to page 19.→ For further information about temperature protection, refer to

page 21.

Introduction

15851-164336 / C

Inspection and unpacking

Inspection

An inspection must be carried out immediately after the unit(s)have arrived at their destination.• Check all wooden or cardboard boxes, plastic bags and palletsfor physical damage. Look for signs of dropping, immersion inwater or other mishandling.

• If damage is detected externally, you will have to open thepackaging to check the contents.- Request a representative of the carrier to be presentwhile thecarton is opened, so any transportation damage can beidentified.

• If any units are damaged, prepare an inspection report statingthe condition of the unit and actions taken.Describe the damageand collect photographic evidence if possible. Send theinspection report to Simrad as soon as possible.

• If the units are not damaged, check the humidity absorbingmaterial. If required, dry or replace the bags, then repack theunit(s) according to the packing instructions.

General unpacking procedure

Normal precautions for the handling, transportation and storage offragile electronic equipment must be undertaken.

Note If the unit is not to beprepared for immediate use, youmay considerstoring it unopened in its original packing material. However, itmay be useful to open the case to check its contents for damage andretrieve any accompanying documentation.

• Check the carton before opening it to ensure it shows no signsof dropping, immersion in water or other mishandling.- If the carton shows signs of such damage, refer to theparagraph covering Inspection on receipt.

• Place the carton on a stable work bench or on the floor with thetop of the carton uppermost.

• In the absence of other instructions, always open the top of thecarton first. The contents will normally have been lowered intothe carton from above, so this will usually be the easiest routeto follow.- Care must be used when opening the carton to ensure thecontents are not damaged.

Caution Do not use a knife to open cardboard cartons - the contents maylie close to the surface, and may be damaged by the blade.

Simrad SP70

16 851-164336 / C

• If the carton has been closed using staples, remove the staplesfrom the carton as you open it. This will reduce the possibilitiesof scratch injury to yourself and damage to the contents.

• If a wooden crate has been closed using screws, always removethem using a screw-driver. Do not attempt to prise the lid offwith a crow-bar or similar.

• Once the carton is open, carefully remove all loose packing andinsulation material. Check for manuals and other documentsthat may have been added to the carton during packing, and putthese to one side. Check also for special tools, door keys etc.

Electronic and electro-mechanical units

Caution Beware of the dangers of Electro-Static Discharge (ESD) both toyourself and to the equipment, when handling electronic unitsand components. Refer to the precautions starting on page 20.

Electronic and electro-mechanical units will normally be wrappedin a clear plastic bag. Lift the unit, in its bag, out of the carton andplace it in a stable position on the floor/work bench.

Note Cables must never be used as carrying handles or lifting points.

Inspect the unit for damage before opening the plastic bag.

Note Do not break the seal to open a circuit board package before theboard is to be used. If the board package is returned to themanufacturers with the seal broken, the contents will be assumedto have been used and the customer will be billed accordingly.

Assuming all is well, open the bag and remove the unit.Open the unit and check inside.Remove anypacking anddesiccantmaterial that may be inside.

Mechanical units

Mechanical units may be heavy. Using a suitably certified liftingapparatus, lift the unit out of the crate and place it in a stableposition on the floor/work bench.

Note Cables must never be used as carrying handles or lifting points.

Inspect the unit for damage and remove any packing material thatmay be inside the unit.

Transducers

Transducers may be supplied mounted to a hull unit (if any), orpacked separately. Crates are normally identified by the ordernumber and the serial number.

Introduction

17851-164336 / C

The transducer face must be protected by a rigid, padded cover(e.g. a wooden box lined with foam rubber) all the time it isexposed to the risk of physical damage.

Note Once the units are unpacked, great care must be taken to ensurethat transducers and cabling are not exposed to any mechanicalstress.

Re-packing

If the unit is not to be installed immediately, re-pack it in its originalpacking material to prevent damage in the intervening period.→ Refer to the information on page 19.

1.8 Storage

Pre-installation storageThe equipment should be stored in its original transportation crateuntil ready for installation. The crate must not be used for anypurpose for which it was not intended (eg. work platform etc.).Once unpacked, the equipment must be kept in a dry, noncondensing atmosphere, free from corrosive agents and isolatedfrom sources of vibration.

Note Do not break the seal to open a circuit board package before theboard is to be used. If the board package is returned to themanufacturers with the seal broken, the contents will be assumedto have been used and the customer will be billed accordingly.

The unitmust be installed in its intended operating position as soonas possible after unpacking.If the unit contains normal batteries, these may have beendisconnected/isolated before the unit was packed. Thesemust thenbe reconnected during the installation procedure. Units containingbatteries are marked.


After use storage

Introduction

If a unit is removed from its operating location and placed intostorage, it must be properly cleaned and prepared before packing.

Simrad SP70

18 851-164336 / C

Cleaning cabinets

If the unit may have been exposed to salt atmosphere while it wasin use, it must be thoroughly cleaned both internally and externallyto prevent corrosion.• Wipe the cabinet externally using a damp cloth and a littledetergent. Do not use excessive amounts of water as the unitmay not be water tight. On completion, dry the unit thoroughly.

• All surfaces must be inspected for signs of corrosion, eg.flaking/bubbling paint, stains etc. Damaged or suspect areasmust be cleaned, prepared and preserved using the correctpreservationmediums for the unit. Themediums to be usedwillusually be defined in the units’ maintenance manual.

• Open the unit, and using a vacuum cleaner, remove all dust etc.from the unit. Great care must be taken to ensure the circuitboards and modules are not damaged in the process.

Mechanical units

If themechanical unit may have been exposed to a salt atmospherewhile it was in use, it must be thoroughly cleaned both internallyand externally to prevent corrosion.• If the construction materials and type of unit permits, wash theunit using a high-pressure hose and copious amounts of freshwater.Examples:- The lower parts of hull units (outside the hull)- Subsea units

• Ensure that all traces of mud and marine growth are removed.Use a wooden or plastic scraper to remove persistent growth,barnacles etc. On completion, dry the unit thoroughly.

Caution Do not use a high pressure hose in the vicinity of cables ortransducers. Do not use sharp or metal tools on a transducerface.

• If the materials or type of unit prevents the use of ahigh-pressure hose, wipe the unit using a cloth dampened withwater containing a little detergent.Example:- The upper parts of hull units (inside the hull)- Hydraulic systems

• Do not use excessive amounts of water as some components onthe unit may not be water tight. Wipe off the detergent with adamp cloth, then dry the unit thoroughly.

Introduction

19851-164336 / C

• All surfaces must be inspected for signs of corrosion, eg.flaking/bubbling paint, stains etc. Damaged or suspect areasmust be cleaned, prepared and preserved using the correctpreservation mediums. The mediums to be used will normallybe defined in the unit’s maintenance manual.

Cables

Wipe clean all exposed cables, and check for damage. If a cableshows signs of wear or ageing, contact Simrad for advice.

Internal batteries

If the unit contains batteries, these may discharge slowly duringstorage. If the unit is to be stored for an extendedperiod, disconnector remove all internal batteries.A suitable piece of insulating material can be placed between thebattery and the electrical contacts to prevent electrical discharge.The battery can then remain in the unit, reducing the risk of it beingmisplaced during the storage period.


Dehumidifier

Place a suitably sized bag of desiccant material (silica gel orsimilar) into the unit to keep the electronic components as dry aspossible.

Coatings

Spray the unit externally with a corrosion inhibitor (e.g. a light oil)before packing.

Re-packingThe unit should be stored and transported in its original packingmaterial and/or crate. In the event that thismaterial is not available,proceed as follows:• Small units must be protected from damp by being placedwithin a plastic bag at least 0.15 mm thick. An appropriatequantity of desiccant material should be placed inside this bag,and the bag sealed. The sealed unit must then be placed in anappropriate carton or crate, and supported in the container byappropriate shock-absorbing insulation (polystyrene foamchips etc.).

Simrad SP70

20 851-164336 / C

• Large units must be placed in a suitable cardboard box orwooden crate. The unit must be protected against physicaldamage bymeans of shock-absorbing insulation mats. The boxmust be clearly marked with its contents, and must be stored ina dry and dust-free area.

• Ensure that the resulting unit is weather proof as required by thecurrent and expected environment.

ESD precautions

Electrostatic Discharge (ESD)

Electro-Static Discharge (ESD) is the transfer of an electrostaticcharge between two bodies at different electrostatic potentials,caused either by direct contact or induction by an electrostaticfield.

The passing of a charge through an electronic device can causelocalised overheating, and it can also “puncture” insulating layerswithin the structure of the device. This may deposit a conductiveresidue of the vaporisedmetal on the device, and thus create a shortcircuit. This may result in a catastrophic failure, or degradedperformance of the device.

ESD Protection during transport and storage

Sensitive electronic equipment must be transported and stored inprotective packing bags, boxes and cabinets. The equipment mustNOT be transported or stored close to strong electrostatic,electro-magnetic or radioactive fields.

Unpacking and servicing ESD sensitive equipment

If it is necessary to open and touch the electronics inside theboxes/cabinets, then the following precautions MUST be taken:

• The working area must be covered by an approvedconductive service mat that has a resistance of between 50kΩand 2 MΩ, and is connected directly to a reliable earth pointvia its earthing cord.

• The service personnel involved must wear a wrist-band indirect contact with the skin, connected to the service mat.

• Printed circuit boards and other components should be placedon the conductive service mat during installation,maintenance etc.

Introduction

21851-164336 / C

Caution If, for any reason, it is necessary to move the circuit board orcomponents from the conductive service mat, they must beplaced in an approved anti-static transportation container (e.g.static shielding bag) before transportation.

• During installation and servicing, all electrical equipment(soldering irons, test equipment etc.) must be earthed.

Temperature protectionIf the unit must be protected against extremes of temperature, thecarton/cratemust be linedonallwalls, base and lidwith 5 cm thickpolyurethane or polystyrene foam.

These units will be identified as delicate in the applicabledocumentation.

The package must then be clearly marked:

Must not be transported or stored in temperaturesbelow -5 degrees Celsius.

Other units can normally be stored in temperatures between -30°Cand +70°C, though refer to the system’s Technical Specificationsdocument for details.

Transducers must not be stored in temperatures below -20°C.

2 INSTALLATION PLANNINGNote For installation in a previously installed trunk system, first read

the information about sonar room requirements. Then, for apreviously installed trunk system, proceed to the Hull Unitinstallation description.

→ Sonar room requirements are described on page 25.→ Installation of the hull unit is described on page 32.

2.1 GeneralThis chapter provides the marine engineers responsible theinformation necessary to plan and install the sonar’s Hull Unitaccording to Simrad’s requirements.Correct installation of the sonar transducer is vital to the system’sperformance. Several variables must be taken into consideration,the most important of which is the vessel’s construction. Thisguide is for use in selecting the best location for the transducer andincludes a brief description of areas to be avoided.

Note Note that installation drawings must be supplied by the shipyard.The installation must be approved by the vessel’s national registryand corresponding maritime authority and/or classificationsociety. The shipowner and shipyard performing the installationare responsible for obtaining and paying for installation approval.

Simrad offers free advice for installation planning. Proposedarrangementsmaybe sent for commentary or suggestions suppliedby Simrad. The following drawings should be submitted shouldassistance be requested:• General arrangement

• Body plan and drawings of relevant bottom tanks andcoffer-dams

• Lines plan

Installation planning

23851-164336 / C

2.2 Location of the Hull Unit

Fore and aftThe Hull Unit should preferably be located within 1/10 to 1/3 thevessel’s Length Between Perpendiculars (LBP)measured from itsForward Perpendicular (FP). Deviations from this rule should notbe made without consulting Simrad.→ The location of the hull unit is indicated in figure 2.

AthwartshipsTheHullUnitmaybe located on theCentreLine (CL)of the vessel,or alongside its keel. If the installation is off-set from the vessel’scentre line, make sure that transducer transmission and receptionwill not be obstructed by the keel.

Figure 2 Location of the Hull Unit

Important considerationsThe Hull Unit trunk must be installed so that it will be verticalunder normal operating conditions.The primary sources of underwater disturbance (other than avessel’s main propeller and bow/sternthruster) that affecttransducer reception are:• Main or bilge keels• Zinc anodes• Cooling elements protruding from the hull• Equipment such as sonar transducers and pitot tubes• Sea chests

Simrad SP70

24 851-164336 / C

• Overboard discharges

• Dents in the hull

All appendages to the hull, indentations and pipe in/outlets arepotential sources of underwater noise. They may act as resonantcavities amplifying noise at certain frequencies, create cavitationor turbulence. Transducers should not be located in the vicinity ofsuch objects and especially not immediately aft of them.


25851-164336 / C

2.3 Sonar room requirements

SizeThe sonar room must be dimensioned to house both the Hull andthe Transceiver Unit. This is due to the limited length of theflexible hose protected cabling (approximately 3.5 m) connectingthe two.A well designed sonar room reduces the risk of corrosion andsimplifies maintenance increasing system reliability. The sonarroom should not be unnecessarily obstructed by girders, pipes etc.which might cause installation problems or impede maintenance.→ Refer to figure 3 on page 27 for an example of a sonar room

arrangement.

Access hatchesThe sonar room must be accessible under all conditions at sea orat a berth. All doors or hatches should be designed so that theequipment can be removed without being disassembled.

LiftingAn attachment point, rated at a minimum of two tons, forsupporting a lifting device should be located above the Hull Unit.This permanently installed fixture will facilitate Trunk and HullUnit mounting and also may be used for service of the equipmentin the future.

HeatingThe sonar room should be equipped with heater, dimensioned tomaintain the equipment within its environmental tolerances (atleast 1000 W), installed close to the deck. Heating is also aneffective method for reducing humidity.→ Refer to page 151 formore information concerning environmental

tolerances.

InsulationBulkheads must be insulated and provided with an interior wall tothe deck. The insulation should be the minimum equivalent of 50mm of rock-wool. In addition, piping passing through the spaceprone to condensation must be insulated.

VentilationThe sonar room should be connected to the vessel’s ventilationsystem. If this is not possible, two 3-inch vents must be providedfrom the sonar room to the main deck.

Simrad SP70

26 851-164336 / C

In the sonar room, the air inlet should be located in close to the deckand the outlet as high as possible. A funnel shaped drip-collectorshould be mounted below the vent pipes to divert moisture to thebilge.On the main deck, the best ventilation is provided when the outletpipe is at least four meters higher than the inlet pipe. To keep outseawater, rain and spray, the ventilation pipes should be fittedwithgoosenecks of the equivalent.

ConduitIf the cable between the wheelhouse and the sonar room passesthrough hatches or areaswhere itmay be damaged, it should be runthrough a conduit (two inch conduit is recommended).

Air vent pipeAn air vent conduit with a minimum of 10 mm internal diametermust be attached to the air bleeding cock on theHullUnit. The pipeshould be laid with with continuous rise to free air on deck orthrough the ship’s side.

Note Through-hull modifications are subject to approval by the vessel’snational registry and corresponding maritime authority. Theshipowner and shipyard are responsible for obtaining installationapproval.

Bilge pumpThe sonar room should be connected to the vessel’s bilge pumpsystem. If this is not possible, a separate bilge pump for the sonarroom must be installed.

LightingThe sonar room should be equipped with suitable lighting tosimplify the installation and aid future maintenance.

Dry dockingMake sure that ample space is provided between the vessel and drydock for system installation. To facilitate future dry docking,markthe position of the installed trunk as indicated.→ Refer to figure 2 on page 23.

DeckingOnce the installation has been completed, the sonar room shouldbe suitably decked without restricting access to the equipment.

67851-164336 / C

7.6 Basic cabling requirements

Cable trays

All permanently installed cables associated with the system mustbe supported and protected along their entire lengths usingconduits and/or cable trays. The only exception to this rule is overthe final short distance (max. 0.5 metre) as the cables run into thecabinets/units to which they are connected. These shortunsupported lengths are to allow the cabinets to move on theirshock mounts, and to allow maintenance and replacements.

• Wherever possible, cable trays must be straight, accessible andplaced so as to avoid possible contamination by condensationand dripping liquids (oil, etc.). They must be installed remotefrom sources of heat, and must be protected against physicaldamage. Suitable shields must be provided where cables areinstalled in the vicinity of heat sources.

• Unless it is absolutely unavoidable, cables should not beinstalled across the vessel’s expansion joints. If the situation isunavoidable, a loop of cable having a length proportional to thepossible expansion of the jointmust be provided. Theminimuminternal radius of the loop must be at least twelve times theexternal diameter of the cable.

• Where a service requires duplicate supply lines, the cablesmustfollow separate paths through the vessel whenever possible.

• Signal cables must not be installed in the same cable tray orconduit as high-power cables.

• Cables containing insulation materials with differentmaximum-rated conductor temperatures should not be bunchedtogether (that is, in a common clip, gland, conduit or duct).When this is impractical, the cables must be carefully bunchedsuch that themaximum temperature expected in any cable in thebunch is within the specifications of the lowest-rated cable.

• Cables with protective coverings which may damage othercables should not be bunched together with other cables.

• Cables having a copper sheath or braiding must be installed insuch a way that galvanic corrosion by contact with other metalsis prevented.

• To allow for future expansion of the system, all cables shouldbe allocated spare conductor pairs.Also, spacewithin the vesselshould be set aside for the installation of extra cables.

Radio Frequency interferenceAll cables that are to be permanently installed within 9 m (30 ft)of any source of Radio Frequency (RF) interference such as atransmitter aerial system or radio cabin, must, unless shielded bya metal deck or bulkhead, be adequately screened by sheathing,braiding or other suitable material. In such a situation flexiblecables should be screened wherever possible.It is important that cables, other than those supplying services tothe equipment installed in a radio room, are not installed througha radio room. Cables which must pass through a radio room mustbe screened by a continuous metal conduit or trunking whichmustbe bonded to the screening of the radio room at its points of entryand exit.

Physical protectionCables exposed to the risk of physical damagemust be enclosed ina steel conduit or protected by a metal casing unless the cable’scovering (e.g. armour or sheath) is sufficient to protect it from thedamage risk.Cables exposed to an exceptional risk of mechanical damage (forexample in holds, storage-spaces and cargo-spaces) must beprotected by a suitable casing or conduit, even when armoured, ifthe cable covering does not guarantee sufficient protection for thecables.Metallic materials used for the physical protection of cables mustbe suitably protected against corrosion.

GroundingAll metallic cable coverings (armour, lead sheath etc.) must beelectrically connected to the vessel’s hull at both ends except in thecase of final sub-circuits where they should be connected at thesupply end only.Grounding connections should be made using a conductor whichhas a cross-sectional area related to the current rating of the cable,or with a metal clamp which grips the metallic covering of thecable and is bonded to the hull of the vessel. These cable coveringsmay also be grounded by means of glands specially intended forthis purpose and designed to ensure a good earth connection. Theglands used must be firmly attached to, and in good electricalcontact with, a metal structure grounded in accordance with theserecommendations.Electrical continuity must be ensured along the entire length of allcable coverings, particularly at joints and tappings. In no caseshould the lead-sheathing of cables be used as the only means ofgrounding cables or units.


69851-164336 / C

Metallic casings, pipes and conduits must be grounded, and whenfitted with joints these must be mechanically and electricallygrounded.

Cable connections

All cable connections are shown on the applicable cable plan andinterconnection diagrams.

Where the cable plan shows cable connections outside anequipment box outline, the connections are to be made to a plug orsocket which suits the plug or socket on that particular item ofequipment.

Where two cables are connected in series via a junction box orterminal block, the screens of both cables must be connectedtogether but not grounded.

Cable terminations

Care must be taken to ensure that the correct terminations are usedfor all cable conductors, especially those that are to be connectedto terminal blocks. In this case, crimped sleeve-terminations mustbe fitted to prevent the conductor core from fraying and making abad connection with the terminal block. It is also of the utmostimportance that where crimped terminations are used, the correctsize of crimp and crimping tool are used. In addition, each cableconductor must have a minimum of 15 cm slack (service loop) leftbefore its termination is fitted.

Cable identification

Cable identification codes corresponding to the cable numbershown in the cable plan must be attached to each of the externalcables. These identification codes should be positioned on thecable in such away that they are readily visible after all panels havebeen fitted. In addition, each cable conductor should be markedwith the terminal board number or socket to which it is connected.

Table 8 Noise measurements

8 When the measurements are finished, make a plot of thenoise for 0 degrees bearing into the Noise speed plot.- The noise level at full speed should preferably not exceedthe 0 dB line.

→ Refer to the plot provided on page 149.This noise/speed curve can give a picture of the ship’s best searchspeed.

Problems with flow noiseIn case of very high ship noise levels, the RCG function willautomatically regulate the receiver gain down. This lower gainwillthen cause a reduction in the receiving range.To find out if this high noise level is caused by flow noise from thevessel’s hull or by the engine/propeller, perform the following test.1 Enter the noise level for 0 degrees bearing from the Noise

measurements table into the column for Stable speed in theNoise verification table.→ The Noise measurement table is given as table 8 on page

147.→ The Noise verification table is given as table 9 .

2 From 0 knots, give full engine thrust, and make a readout ofthe noise level for Acceleration when the vessel reacheseach of the listed speeds. Enter the readouts into the table.

3 From full speed, reduce the engine thrust for minimumspeed, and make similar readouts for Retardation.
